Mechanical structure of dual-loading-mode grinding and polishing machine driven by electric push rod

Abstract

The invention discloses a mechanical structure of a dual-loading-mode grinding and polishing machine driven by an electric push rod. The mechanical structure of the dual-loading-mode grinding and polishing machine driven by the electric push rod is composed of a machine head, a vertical column and a base. The machine head can be controlled manually to rotate around the vertical column and can be reliably locked in a working position. The mechanical structure of the dual-loading-mode grinding and polishing machine driven by the electric push rod comprises two loading modes of a single-point force mode and a middle force mode, the middle force mode is achieved though the integrated descending and pressing of a working head to process a batch of samples with a same depth, and the single-point force mode is achieved through the pressing of an independent cylinder driven by a group of independent air pumps press to process the same batch of samples with different depths. The electric push rod is utilized as the power mechanism and the transmission mechanism for lifting the machine head as well as the force application mechanism and the force adjusting mechanism in the middle force mode; and the machine head can be driven by the electric push rod to move vertically along the vertical column and is matched with the use of a force sensor to achieve controlling the magnitude of the loading force. The mechanical structure of the dual-loading-mode grinding and polishing machine driven by the electric push rod is simple in structure, high in automation degree, processing precision and working efficiency, easy to operate and high in commutativity.

AI Technical Summary

Problems solved by technology

[0003] At present, the grinding and polishing equipment on the market has the following limitations: the lifting mechanism mostly adopts the traditional screw nut mechanism. The rise in temperature leads to thermal deformation of the lead screw, resulting in non-negligible thermal errors; during the grinding and polishing process, the loading force needs to be manually adjusted through mechanical devices, which can neither save processing time nor accurately control the process parameters of the processing process; machine parts The replaceability is not high, resulting in a short service life of the whole machine, and it is difficult to save costs
